known and/or possible rogue planets (Planemos)Planemos are a bit... bland, in my opinon but I made this anyway (Might add hypothetical moons later, just to make it more interesting)Planemos.sc goes in addons/catalogs/starsRougePlanets.sc goes in addons/catalogs/planets

[color=#ffffff]Recently astronomers suspected existence of the exomoons around 1SWASP J1407 b, WASP-12 b, Kepler-1625 b and especially MOA-2011-BLG-262L (on https://en.wikipedia.org/wiki/exomoon). They were able to confirm 1SWASP J1407 b as a Super Jupiter with a largest ring system, Kepler-1625 b as a Super Jupiter with Neptune-sized exosatellite, and MOA-2011-BLG-262L as a red dwarf with a ringed exoplanet (but not a rogue planet). They are not so sure about WASP-12 b's unknown exosatellite. More detailed observations by Leiden Observatory and University of Rochester researchers were able to determine that J1407 b's ring system consist of 37 icy-rocky rings (~1.0 Earth Mass) and major 16 ring gaps out to distance of 0.58 A.U. (on https://iopscience.iop.org/article/10.1 ... /2/126/pdf). They believed that one large exomoon wiht less than 0.8 Earth Mass resides in a large ring gap at 0.4 A.U. and two smaller exomoons with at least 0.3 Earth Mass each one resides in two small ring gaps at 0.23 and 0.24 A.U. respectively. However, presence of more ring gaps less than 0.4 A.U. to primary planet's cloudtops may indicate possible 6-7 exomoons all with 0.3 Earth Mass each one, based on the model structure of Kepler-90 system. Clearing of the ring gaps in a circumplanetary disk by protosatellites around the large Jovian planet show that the planetary formation can be very rapid. Extinct isotopes of Technetium-97, -98 and -99 decaying into Molybdenum-97, Ruthenium-98 and Ruthenium-99 in our early Solar System with half-lives of 3.4 million years, 4.2 million years and 210,000 years respectively. Two distinct reservoirs of such Mo-97 and Ru-98 isotopes in the iron meteorites (iron groups I, II, III & IV) show that large planetesimals and SuperEarths accrete in only 200,000 to 7 million years before being destroyed by Jupiter (also accreting at the same time) in the Grand Tack Event, with decay products retained; whereas terrestrial planets like Venus, Earth and Mars formed from demolition debris belt for few tens of million years after the Grand Tack, with no decay products retained. Jupiter separates the molybdenum isotope sources in the inner zone of Solar Nebula from those in the outer zone (on http://www.sciencedirect.com/science/ar ... 1x16305003 and news.brown.edu/articles/2016/12/jupiter). We are so fortunate to witness such unique event of large exomoons forming (or already formed) around a Super Jupiter soon after the primary star's birth as the nebula dissipated. A large Jovian planet probably tipped by another planet (yet unseen) on its inward migration to the star and captured sufficent amount of at least 2.8-3.0 Earth Mass from that object and even asteroid belt in the early stages of planetary formation in J1407's history. Such material could quickly accrete into seven Mars-sized rocky ice exomoons and one Earth-sized Titan exomoon as Jupiter's Galilean Moons and Saturn's Moon Titan (both larger than Planet Mercury) can demonstrate.

I had worked on making and fine-tuning the orbital and physical parameters of such eight exomoons for one week- using the following: Earth Mass= 5.9736e24 Kg; Jupiter Mass= 1.8989e27 Kg (318 Earth Mass); and J1407 b Mass= 3.8004e28 Kg. Therefore, Moon + Planet= Total Mass in Kilograms and Orbital Distance + Planetary Radius= Total Height above Center of Mass in Meters. I use Kepler's 3rd Law Ultra Calculator online on http://www.1728.org/kepler3a.htm. Therefore,*Selena bI, volcanic Super Io, 1.93306056e9 m, 3.80061877e28 kg= period 3.8808 days or 0.010625 years*Terra bII, like early Earth, 5.89206056e9 m, 3.80058956e28 kg=period 20.651 days or 0.056539 years*Terra bIII, like early Earth, 1.459006056e10 m, 3.8005225e28 kg= period 80.47 days or 0.22031 years*Iceworld bIV, like volcanic Super Europa, 2.831406056e10 m, 3.80054742e28 kg= period 217.55 days or 0.5956 years*Iceworld bV, like volcanic Super Europa, 3.3660064e10 m, 3.8005746e28 kg= period 281.98 days or 0.77201 years*Oceania bVI, with still freezing sea, 3.5200064e10 m, 3.80058743e28 kg= period 301.55 days or 0.82559 years*Titan bVII, like Super Titan, 4.83500064e10 m, 3.80062096e28 kg= period 485.45 days or 1.3291 years*Titan bVIII, like Super Titan, 6.1200064e10 m, 3.80081448e28 kg= period 691.30 days or 1.8926 years[/color]

[color=#ffffff]J1407 b's exomoons would be placed at the random distances anywhere below Gap N. But not every gap has a exomoon. The other stellar systems with more than 5 exoplanets are placed here for comparison. Super Jupiters have a greater chance of Mars-sized and Earth-sized exomoons with massive helium-nitrogen atmospheres with greenhouse gases like H2O, SO2, NH4 and CH3 to be discovered by our future explorations. Terra exomoons have a good chance of becoming the "Gas Dwarfs" size of Neptune if they retain more H2 or He. J1407 b's eight exomoons are not officially confirmed yet, until the James Webb Space Telescope would be launched in 2018.[/color][color=#ffffff]1SWASP J1407 b.sc goes in addons/catalogs/planets

This exoplanet has largest rings that extend to 0.5 A.U. and orbits around a star called J1407 400 light years from our Sun. For comparison, Saturn's rings extend to only 0.001 A.U. but there is a equatorial ridge on a distant moon Iapetus that once get dust and rock from much more massive ring system out to distance of 0.25 A.U., almost to half way like J1407 b ring system many billions of years ago. Saturn's smaller icy moons accrete at much later date than Iapetus and Titan. I do believe that Jupiter's Galilean moons and Saturn's moon Titan formed first, long before our Moon was made.
